The present invention is a continuation-in-part of application Ser. No.14/485,673, filed on Sep. 13, 2014.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shoe sole structure of a cyclingshoe, and more particularly to a shoe sole structure of a cycling shoefor bicycles that may enable a user's foot to completely fit with theshoe sole structure of the cycling shoe, may reduce the friction betweenthe user's foot and the shoe sole structure to enhance the forcetransferring effect of the user's foot, and may provide a ventilationeffect for the user when wears the cycling shoe for cycling.

2. Description of Related Art

Conventional shoes have different kinds and uses such as running shoes,basketball shoes, leather shoes or cycling shoes. A conventional runningshoe is disclosed in U.S. Pat. No. 4,689,898. The conventional runningshoe has a sole, a shoe surface, and an insole. The sole is made of softmaterials and may deform when a user wears the conventional running shoeto run. The shoe surface is connected to the sole to form a receivingspace for the user's foot. The insole is mounted in the receiving spacebetween the sole and the shoe surface, is deposited on a top side of thesole, and may have multiple arch supports formed on a top surface of theinsole to abut a bottom surface of the user's foot. Although the archsupports of the insole may enable the top surface of the insole to abutwith the bottom surface of the user's foot. However, the materials ofthe sole and the insole of the conventional running shoe are soft, andthe sole and the insole may be deformed when the user wears theconventional running shoe to run. Since the sole and the insole aredeformed when the user is ran, and the arch supports cannot completelyabut with the bottom surface of the user's foot, and tis may increasethe friction between the insole and the user's foot. Then, the forcetransferring effect of the user's foot is limited and cannot fullytransfer to the conventional running shoe. Therefore, the conventionalrunning shoe cannot be used on a bicycle for racing since theconventional running shoe may be deformed and may be slid from a pedalof the bicycle, and the conventional running shoe didn't have anyengagements to engage with the pedal of the bicycle.

Furthermore, with reference to FIG. 17, a conventional cycling shoe 70has a sole 71 and an insole 72 deposited in the conventional cyclingshoe 70, and the insole 72 has a heel area 721, an arch area 722, and ametatarsus area 723, that are connected with each other sequentially. Inuse, with reference to FIG. 18, when a user rides a bicycle by theconventional cycling shoe 70, the heel, the arch, and the metatarsus ofthe user's foot are respectively corresponding to and abut on the heelarea 721, the arch area 722, and the metatarsus area 723 of the insole72 of the conventional cycling shoe 70. When the user wants to increasethe speed of the bicycle, the metatarsus area 723 and a location betweenthe metatarsus and the toes of the user's foot are forced on theconventional cycling shoe 70 to transfer force to the bicycle via theconventional cycling shoe 70.

However, the location between the metatarsus and the toes of the user'sfoot isn't completely touch or press on the insole 72 and a space isformed between the location and the insole 72 of the conventionalcycling shoe 70. When the user wants to speed the bicycle with pressingthe location on the insole 72, the location between the metatarsus andthe toes of the user's foot may slid relative to the insole 72 andincrease the friction between the user's foot and the insole 72. Then,the force of the user's foot cannot be fully transfer to the bicycle viathe conventional cycling shoe 70, and this will influence the efficiencyand performance of the user.

In addition, the ventilation effect of the conventional shoe is limited,and is only provided by forming holes through the shoe surface of theconventional shoe rather than having any ventilation structuresdeposited on the sole of the conventional cycling shoe. For example,when the user wears a conventional cycling shoe 70 to ride a bicycle,the exercise of the user is high and the use's foot may produce moresweat to accumulate moisture in the sole 71 and the insole 72 withoutdischarging from the sole 71, and the user may feel uncomfortable whenwearing the conventional cycling shoe 70 to ride the bicycle. The shoesole structure of a cycling shoe for bicycles in accordance with thepresent invention mitigates or obviates the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a shoe solestructure of a cycling shoe for bicycles that may enable a user's footto completely fit with the shoe sole structure of the cycling shoe, mayreduce the friction between the user's foot and the shoe sole structureto enhance the force transferring effect of the user's foot, and mayprovide a ventilation effect for the user when wears the cycling shoefor cycling.

The shoe sole structure of a cycling shoe for bicycles has a sole and aninsole. The sole is made of rigid materials without deforming, and has acurvature, at least one engaging hole, and at least one ventilatinghole. The insole is made of soft materials, abuts against a top surfaceof the sole, and has a curvature, a heel portion, an arch portion, ametatarsus portion, and a toe portion. The curvatures of the sole andthe insole are corresponding to a curvature of a bottom surface of auser's foot. When the insole is deposited in the cycling shoe and abutsthe sole, and the user's foot wears the cycling shoe and the weight ofthe user's foot is applied on the insole and the sole of the cyclingsole, since the material of the insole is softer than the material ofthe sole to enable the insole to deform, and the weight of the user'sfoot is pressed on the insole, and the insole completely abuts theuser's foot and the sole without forming any interspaces between theuser's foot and the sole.

The curvature of the sole 10is formed on the sole 10 from the heel end to the toe end of the sole 10between the bottom surface and the top surface of the sole and iscorresponding to a curvature of a bottom surface of a user's foot. Inaddition, since the curvature of the sole 10 is corresponding to thecurvature of the bottom surface of the user's foot, and the curvature ofthe sole 10 is undulating. The at least one engaging hole 11 is formedthrough the bottom surface and the top surface of the sole 10 adjacentto the toe end of the sole 10 to engage a protrusion of a pedal of abicycle. Then, the sole 10 can be surely deposited on the pedal by theengagement between the at least one engaging hole 11 and the protrusionof the pedal. The at least one ventilating hole 12 is formed through thebottom surface and the top surface of the sole 10 adjacent to the heelend of the sole 10 to provide a ventilating effect.

With reference to FIGS. 2 and 4, the insole 20 is made of soft materialssuch as foam, abuts against the top surface of the sole 10, and has aheel end, a toe end, a curvature, a heel portion 21, an arch portion 22,a metatarsus portion 23, a toe portion 24, and a strengthening portion25. The curvature of the insole 20 is formed on the insole 20 from theheel end to the toe end of the insole 20 and is corresponding to thecurvature of the bottom surface of the user's foot. Then, the user'sfoot may fully abuts with the sole 10 via the insole 20. The heelportion 21 is deposited on the insole 20 at the heel end of the insole20. The arch portion 22 is formed with the heel portion 21. Themetatarsus portion 23 is formed with the arch portion 22 and is oppositeto the heel portion 21. The toe portion 24 is deposited on the toe endof the insole 20 and is formed with the metatarsus portion 23.Additionally, the curvature of the insole 20 is formed between the heelportion 21, the arch portion 22, the metatarsus portion 23, and the toeportion 24.
